CATCH DEVICE.

Application filed December 1, 1924. Serial No. 753,230.

To all whom it may concern:

Be it known that I, HARRY J. W. TRAU- MI'iLLnR, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improve ments in Catch Devices, of which the fol? lowing is a specification, such as will enable those skilled in the art to which it appere tains to make and use the same.

This invention relates to catch devices and particularly to spring actuated catch devices for use in connection with jewelry cases of various kinds and classes, such for example, as watch cases, ring cases or in connection with pipe cases and other small box members used as containers for small articles for the purpose of retaining a hinged cover in closed position and with means for releasing the catch member to permit of the opening of the cover; and the object of the invention is to provide a device of the class and for the purpose specified which is so constructed as to facilitate the mounting thereof in connection with cases of different size, construction and dimensions whereby the catch device may be universally applied to cases of the class specified; a further object being to provide simple and effective means for securing the catch device in position and further to the provision of means for reinforcing a case where the catch device is secured thereto when the case is composed of cardboard or other light material; and with these and other objects in View, the invention con sists in a device of the class specified which is simple in construction and operation, efficient in use and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig. 1 is a sectional View through a portion of a case showing one form of my improved catch device mounted in connection therewith and with part of the construction in section. a

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 33' of Fig. 2.

Fig. 9 is a partial section on the line 9-9 of Fig. 7.

In Figs. 1 to 4 inclusive, I have shown one form of clasp device comprising a clasp arm 10 preferably fashioned from sheet metal and provided at one end with an Oilset portion 11 adapted to engage a catch plate or the like12 securedto the cover 13'of a box or case 14 as seen in Fig. 2, and mounted in connection with the lower end portion of the arm 10' is a tubular plunger 15, the outer end of which'is closed as shown at 16, and the inner end portion of which is divided by a transverse slide 17 into separate members 18, the reduced ends 19 of which pass through apertures 20 in the arm 10 and are bent upon the outer face of said arm to retain said parts together with the arm 10 extending at right angles to the plunger 15.

Prior to securing the parts 10 and 15 together, a mounting plate 21 is mounted up on the members 18, said members extending through apertures 22 formed in the plate as clearly seen in Fig. 3 of the drawing. The plate 21 is of greater transverse width than the arm 10 and is provided with outwardly directed V-shaped prongs 23 at the upper outer corner portions thereof, which prongs are adapted to be passed into and through the case or box member 14 and the pointed ends of which are riveted or bent over upon the outer face of the case or box 14 as shown at 24 in Fig. 1 of the drawing.

A coil spring 25 is also placed within the tubular plunger 15 before the parts 15 and 10 are connected and this spring bears upon the closed end 16 of the plunger and the plate 21 and the spring normally serves to hold the plunger and arm 10 in extended or foremost position or to hold the arm 10 orthe offset portion 11 thereof in engagement with the plate 12 to retain the cover 13 of the box member-14; in closed position.

The attaching or mounting plate 21 is also preferably provided at the opposite side portions thereofwith apertures "26 and in Fig. 5 of the drawing, the prongs 23 are Omitted In unting the .19 in toss s: tion with the box member and look, a retaining element 27 is employed, the same being in the form of an eyelet having a central aperture 28 to receive the plunger 15 and provided with inwardly directed fingers 29 adapted to be passed through the'box member 14 and the apertures 26 in the plate 21v and to be bent laterally in the manner shown in Figs. 5 and 6 of the drawing for retaining the plate in connection with the box member and for reinforcing the box member at the point of attachment The construction shown in Figs. 5 and 6 is designed particularly for use in connection with carboard or other lightly constructed boxes or cases, and in this construction the prongs 23 may or may not be employed.

In the construction shown in Figs. 7 to 9 inclusive, I have shown a slight modification wherein the parts 10 and 15 shown in Figs. 1 tot inclusive areformed integral in a part 30, comprising a tubular plunger portion 31 similar to'the plunger 15 and a catch arm 32 extending at right angles to the innerend of the plunger 31 and having an offset portion 33, said arm' being formed integral with the plunger as clearly seen on a consideration of Fig. 7 of the drawing. YVith this construction, the lunger 31 "is provided adjacent the arm 32 withoppos'itely disposed'apertures'3t a nd theplate 21 which is similar in all respects to the plate 21 shown in Figs. 1 to 6 inclusive, with the exception of the central formation thereof, is mounted'upon the plunger 31'as hereinafter set out. i

The plate '21 is provided centrally thereof with an aperture '35 to receive'an'd permit of the passage of the plunger 31 there through, said plate having 'o'ppositely'disposed tongue members 36 integral therewith and adapted to be bent inwardly and to extend into the aperture 35 as seen in'Figsf'T and 8 of the drawing to form a seat for the coil spring 37 in the plunger 31, and the tongue members 36 are movable through the apertures 34 of the plunger 31 as will be apparent. It will be understood that the spring 37 must first be placed in the plunger 3l and the'tongue members moved inwardly when the spring is held in a compressed position. r a

It will be understood that with the con struction shown in Figs. 7 to 9 inclusive, the entire device is composed of two main parts and a spring, instead of three main parts and a spring as shown in Figs. 1 to 6 inclusive, and it will also be apparent that the structure shown in the latter figures may bemou'nted as in the manner shown in Figs.

5 and 6 of the drawing or in any other desired' nanner within the scope of the invention.

With all of the forms of construction share the dis in v t e e Of y invenreferenceto' the lock plate 12 secured to the cover member 13 of the case or box. WVith the aperture 141?, and plate 12 in predetermined spaced relation on the separate members of the case, my improved catch device may be readily mounted in position without any change in the construction thereof or without necessitating the manufacture of the same in numerous sizes as is the present custom in devices of this class, and while I have shown and described certain details of construction for carrying my invention into effect, it will be understood that I am not necessarily limited to the constructions herein shown and described and various changes therein and modifications thereof may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters-Patent, is

1. A catch device of the class described comprising a mounting plate, a tubular plunger part and a catch arm extending radially from said plunger part adjacent one end thereof, the other end of said'plunger part being closed, a coil spring mounted in said plunger part and cooperating with a portion'of said mounting plate extending into said part and serving to normally hold the catch arm in operative position when the device is in use.
